| 摘要 | A method is described of using a mapping between a session initiation protocol (SIP)-Uniform Resource Identifier (URI), local IP address and a global IP address to identify a mobile host attached to a first subnet of a plurality of subnets included in a network domain, receiving a new local IP address of the mobile host upon the mobile host attaching to a second subnet of the plurality of subnets, replacing the local IP address with the new local IP address in the mapping, reformatting routing information of a SIP packet by replacing the global IP address in the routing information with the new local IP address, and communicating the reformatted packet to the mobile host. A proxy server and apparatus for use in this method are also disclosed. | ||
